Hi All,

Just wondering if anyone knows of some kind of command that displays how
my ext3 filesystem is doing it's journal? What I am looking for
specifically is the data= information. I understand that the three modes
are writeback, ordered and journal. I just want to be able to find out
what my filesystems are using.

Thank you,

Phil

It's a mount option (cf. man mount). data=ordered is the default

Kind regards,

Herta

Hi Herta,

I understand that and did look at the mount man page, but was just wondering
if there was a command that would give information about how the journaling
is employed on the filesystem

The mount command will tell you. Look at this example:

# mount |grep boot
/dev/sda1 on /boot type ext3 (rw)
# umount /boot
# mount -o data=writeback /boot
# mount |grep boot
/dev/sda1 on /boot type ext3 (rw,data=writeback)

The first command didn't show the mode, so the default data=ordered applies.

Kind regards,

Herta
